The aim of this document is the description of typical hardware solutions useful for developing a

product with the Telit CE910 module.

In this document all the basic functions of a mobile device will be taken into account; for each one of

them a proper hardware solution will be suggested and eventually the wrong solutions and common

errors to be avoided will be evidenced. Obviously this document cannot embrace all hardware

solutions and products that may be designed. Avoiding the discussed wrong solutions must be

considered as mandatory. While the suggested hardware configurations must not be considered

mandatory, the information given must be used as a guide and a starting point for properly developing

a product with the Telit CE910 module.

NOTE:

The integration of the CDMA 1xRTT module within a user application must be done according to the

design rules described in this manual.
